ACR Test for Kidneys | What It Is, What It Costs and Why It Matters
Share
Foamy or frothy urine is one of the earliest visible signs of protein leaking from damaged kidneys — and the ACR test (Albumin-Creatinine Ratio test) is the most sensitive method to confirm this, often detecting kidney damage years before symptoms appear. If you have diabetes, high blood pressure, or a family history of kidney disease, this simple urine test could protect your kidney function for life. healthcare nt sickcare in Aundh, Pune offers the ACR test online at an affordable price with home sample collection across Pune.

What Is the ACR Test for Kidneys?
The ACR test (Albumin-Creatinine Ratio test) is a urine test that measures how much albumin — a key blood protein — is leaking into the urine relative to creatinine levels. Healthy kidneys retain albumin in the bloodstream; when kidney filters are damaged, albumin spills into urine, raising the ACR above normal.
Micro-definition: Albumin-Creatinine Ratio (ACR) = milligrams of albumin per gram of creatinine in a spot urine sample. An ACR above 30 mg/g on two or more separate tests confirms kidney damage, as per international KDIGO (Kidney Disease: Improving Global Outcomes) clinical guidelines.
The ACR test is also called the microalbumin test, urine microalbumin creatinine ratio test, or UACR test — all referring to the same investigation. It is a cornerstone of early chronic kidney disease (CKD) detection and an important marker for non-communicable disease risk assessment in India. Read our complete guide on how to assess kidney health for a broader overview of renal function testing.
Why Is the ACR Test Done? Key Reasons
The ACR test is done to detect early kidney damage before blood creatinine or eGFR levels become abnormal — giving patients and doctors a critical head start to slow or reverse kidney disease progression.
- Early detection of diabetic nephropathy — Diabetes is the leading cause of kidney failure in India. Elevated ACR is the first detectable sign of diabetic kidney damage, often appearing 5–10 years before clinical kidney disease. Learn how to test for diabetes and its kidney complications together.
- Hypertension-related kidney monitoring — Chronically high blood pressure damages the delicate glomerular capillaries in the kidneys. Regular ACR testing tracks this silent damage. See our guide on testing for hypertension and its effects on kidney health.
- Cardiovascular risk stratification — Elevated ACR is independently associated with increased heart attack and stroke risk, even in individuals without known kidney disease.
- Monitoring CKD progression — For patients already diagnosed with chronic kidney disease, serial ACR measurements guide treatment decisions and medication adjustments. Review our detailed explanation of kidney function tests to understand how ACR fits into the broader renal panel.
India has over 77 million adults living with diabetes, making routine ACR screening a public health priority — particularly in urban Maharashtra, where sedentary lifestyles and high-salt diets compound cardiovascular and renal risk.
Who Needs an ACR Test?
An ACR test is recommended annually for anyone with diabetes or high blood pressure — and for all adults above 40 with risk factors for kidney disease in Pune and across India.
- Adults with Type 1 or Type 2 diabetes — annually from diagnosis
- Adults with hypertension or metabolic syndrome
- Anyone with a family history of kidney disease or polycystic kidney disease
- Adults above 40 for routine preventive renal screening
- Those experiencing swelling (oedema), persistent fatigue, foamy urine, or changes in urination frequency
- Post-COVID patients monitoring organ recovery
- Individuals on long-term NSAIDs, antibiotics, or other nephrotoxic medications
The test is non-invasive, requires no fasting, and only needs a small spot urine sample — making it suitable for young adult preventive health screening as well as senior health monitoring.
How Is the ACR Test Performed?
The ACR test uses a spot urine sample collected using the clean-catch mid-stream technique — no fasting, no injections, and no special preparation beyond a few simple precautions.
Sample Collection Instructions
- Collect a mid-stream urine sample (discard first and last portions of the urine stream)
- Avoid heavy physical exercise for 24 hours before the test — exertion temporarily raises urinary albumin levels
- Avoid eating large amounts of red meat or high-protein meals the night before
- Do not test during active urinary tract infection, fever, or menstruation — these can falsely elevate albumin
- Inform your doctor about any medications, including ACE inhibitors or ARBs, which affect ACR results
At healthcare nt sickcare in Aundh, Pune, the direct walk-in facility is available Monday to Saturday, 8:45 AM to 6:00 PM. Home sample collection is available across Pune — including Baner, Wakad, Kothrud, Pimpri-Chinchwad, Hadapsar, and Shivajinagar — with same-day or next-day slots. Read our guide on how to prepare for a lab test before your visit.
What Do ACR Test Results Mean?
ACR results are reported in milligrams of albumin per gram of creatinine (mg/g) — and a result above 30 mg/g on two separate occasions is clinically significant for kidney disease assessment.
| ACR Result (mg/g) | Category | Clinical Significance |
|---|---|---|
| Less than 30 | Normal | Kidney filters functioning normally |
| 30–299 | Moderately Increased (Microalbuminuria) | Early kidney damage — treatable with lifestyle changes and medication |
| 300 or above | Severely Increased (Macroalbuminuria) | Advanced kidney damage — specialist nephrology review needed |
A single elevated result does not always confirm kidney damage — transient elevations can occur after intense exercise, fever, or dehydration. A confirmatory repeat test within 3 months is standard practice before a diagnosis of CKD is confirmed. Pair ACR results with a renal function test kidney profile (serum creatinine, BUN, eGFR) for a complete picture of kidney health. Understanding what kidney failure means in context of these results is covered in our kidney failure video explainer.
ACR Test Price in Pune
The ACR test price at healthcare nt sickcare in Aundh, Pune is ₹599 for the urine ACR test. Home sample collection is available for an additional ₹130. The microalbumin creatinine ratio test can also be booked as part of a bundled kidney function test package for better value when multiple renal tests are needed simultaneously.
ACR Test vs Other Kidney Tests: What Is the Difference?
The ACR test detects early kidney damage through urine protein leakage, whereas blood-based tests like serum creatinine and eGFR only become abnormal once 50% or more of kidney function is already lost — making ACR the superior early warning tool.
- ACR vs Urine Routine Microscopy — Standard urine routine detects gross proteinuria; ACR is specifically quantitative for albumin, catching microalbuminuria that urine dipstick misses.
- ACR vs Serum Creatinine / eGFR — Blood creatinine and eGFR measure current filtration rate; ACR detects structural glomerular damage before filtration rate drops.
- ACR vs 24-Hour Urine Protein — The creatinine clearance test using 24-hour urine collection is more precise but cumbersome; the ACR spot test offers equivalent clinical accuracy for most screening and monitoring purposes.

How ACR Testing Helps Manage Diabetes and High Blood Pressure
Diabetic nephropathy — kidney damage caused by high blood sugar — is the most common reason for dialysis in India, and it is almost entirely preventable when detected at the microalbuminuria stage. The ACR test is the only currently validated method to detect this damage before it becomes irreversible.
Similarly, hypertensive nephrosclerosis, the kidney damage caused by sustained high blood pressure, progresses silently for years. Annual ACR testing for anyone on antihypertensive medication is considered standard of care by the World Health Organisation (WHO). Explore our diabetes test packages and hypertension test packages to bundle ACR with your routine monitoring investigations.
People Also Ask About the ACR Test for Kidneys
The ACR test (Albumin-Creatinine Ratio test) is a urine test that detects early kidney damage by measuring how much albumin protein is leaking into the urine. In healthy kidneys, albumin stays in the blood. When kidney filters (glomeruli) are damaged — typically by diabetes, high blood pressure, or inflammatory kidney disease — albumin leaks into urine in small but measurable amounts. An ACR above 30 mg/g indicates early kidney damage (microalbuminuria), which is a critical and actionable finding. The ACR test for kidneys is considered the gold-standard early screening tool for diabetic nephropathy and hypertensive kidney disease worldwide.

The ACR test does not require fasting. It uses a spot urine sample collected using the clean-catch mid-stream technique — you discard the first few drops of urine and collect a sample from the middle of the urine stream into a sterile container. The process takes under a minute. However, avoid strenuous exercise 24 hours before the test, do not eat a large meat-heavy meal the previous night, and avoid testing during a urinary tract infection, menstruation, or fever, as these conditions temporarily raise albumin levels and can produce misleading results. Home collection is available if you prefer to collect the sample at home.
An ACR between 30 and 299 mg/g (called microalbuminuria or moderately increased albuminuria) indicates early kidney damage that is still treatable and often reversible with proper blood sugar and blood pressure management, dietary changes, and medication such as ACE inhibitors or ARBs. An ACR of 300 mg/g or above (macroalbuminuria) indicates more advanced kidney damage and requires specialist nephrology review and a comprehensive renal function workup. A single elevated result should be confirmed with a repeat test within 3 months, as transient elevations can occur after exercise, illness, or dehydration. Always discuss your results with a qualified physician or nephrologist.
All adults with Type 1 diabetes should begin annual ACR testing 5 years after diagnosis. Adults with Type 2 diabetes should start annual ACR testing at the time of diagnosis, as some may already have microalbuminuria at diagnosis due to the slow, silent onset of Type 2 diabetes. Adults with hypertension should have an ACR test at least once a year as part of their renal function monitoring. If the ACR result is elevated, more frequent testing (every 3–6 months) may be recommended by your doctor to track progression and treatment response. Regular testing is the most cost-effective way to prevent progression to kidney failure and dialysis.
Yes, the ACR test and the microalbumin test refer to the same investigation. The microalbumin test measures the concentration of albumin in urine, while the ACR (Albumin-Creatinine Ratio) test expresses albumin as a ratio to urinary creatinine — correcting for urine concentration and making the result more reliable regardless of hydration status. At healthcare nt sickcare, the test is listed as the Urine ACR Test (microalbumin creatinine ratio) and is the preferred method recommended by international guidelines over standalone microalbumin testing. Both tests are performed from the same urine sample.
Yes — particularly at the early microalbuminuria stage (ACR 30–299 mg/g), kidney damage is often reversible or stabilisable with targeted interventions. These include strict blood sugar control in diabetes (targeting HbA1c below 7%), tight blood pressure management (target below 130/80 mmHg), prescription of ACE inhibitors or ARBs which reduce glomerular pressure, a low-salt diet, regular moderate exercise, quitting smoking, and maintaining a healthy body weight. Studies show that reducing ACR by 30–50% with treatment significantly lowers the risk of progression to kidney failure. Early action is critical — the window for reversal narrows as ACR rises above 300 mg/g.
